Truck losing volts on battery

Have you had the battery checked? It may not be able to hold a charge. Otherwise you have a parasitic draw. This video will show you how to check for this... www.youtube.com/watch?v=QRso1A0VScw

New alt & starter what about the battery? Check ground(s) and battery terminals & wires. May have parasitic draw.
I got the battery checked 3 times AutoZone said it was good
If the battery is draining due to running the truck then the charging system is not working. IF the battery is draining with the truck turned off then you have a parasitic draw.
I think u guys are right there is a radar detector hooked up and aftermarket switches. Watching this video has made me see a new point of view. Ill keep u updated on my progress i got to do some testing tomorrow
